.There is a rectangular Garden whose length and width are

Area of walkway is 516m^2. Find width of walkway:
1 2 3 4
Answer Posted / ravindra sharma
total area = 1200
area of walk way = 516 (given)
area of remaning part(R)(with out walkway path area)
=1200-516
=684
let,
length= l
width= b
area or R=>l*b =684
but,
l=60-2x (x is width of the walk way)
b=20-2x
so,
(60-2x)*(20-2x)=684
=> (x^2)-40x+129=0
=> x=36.46 (not possibal)
and
x=3.5379(so ans is 3.5)
